Abstract:

We have prepared a homologous series of polymers, BP-CO4-On (n= 3-15). [ILLEGIBLE] The BP-CO4-On polymers are classified as a new type of main-chain liquid crystalline polymer, characterized by having the mesogenic biphenyl moieties and the two different aliphatic spacers incorporated in a regularly alternate fashion. All the polymers form a smectic A phase. The smectic behaviour and structure have been examined by differential scanning, optical microscopic and x-ray methods, concentrating on how the two spacers, which are different in length and of odd-even nature, are accommodated into a sme

Abstract:

This work consisted in the preparation and the study of a new stationary phase based on liquid crystals for gas chromatography applications. Most of the synthesized compounds that have the character of liquid crystals in their constitution include aromatic molecules. In addition, there is little work that replaces this type of molecules with heterogeneous molecules that have a liquid crystalline character. This study constitutes an approach for the synthesis of a new molecule azoesters involves a 1,3,4-oxadiazole unit instead of aromatic rings, and which exhibits liquid crystalline characters.
